Sleep!!!

Do rabbits sleep more as they get older? Everytime I went into the rabbits bedroom today they were fast asleep noses twitching and everything bless them. They are only 4 1/2 so I wouldn't really class them as old but I suppose they are not babies anymore!

What was the weather like? My Artie is about four and he's spent nearly all day curled up in his pet bed. With him it tends to be -
nice weather = playful/sunbathe
dull and cold = stay in bed all day.

I suppose they do slow down as they get older?? I've often wondered how much to expect they to 'play' as they get older, as well as the sleeping stuff. I know my bunnies are particularly lively at 5.00 am at this time of year, perhaps they get it out of their system then!!
